| Abstract: | The activated carbon （AC） is treated by vacuum impregnation using various surfactant. The acti- vated carbon treated with surfactant is characterized by Fourier transform infrared spectroscopy, thermal gravity analytical, and electrochemical measurements. The enhancement in electrochemical performance of treated AC e- lectrode is mainly attributable to improvement in wettability and ion mobility, resulting in a higher usable surface area and a smaller internal resistance. The AC electrode supercapacitor treated with sodium dodecylbenzene sul- fonate exhibits the best electrochemical performance. Specifically, its specific capacity by the 143.2 F g-1 in- creased to 196.8 F g-1, internal impedance by the 1.75 Ω reduced to 0.71Ω and maximum power density by the 6035.7 W kg- 1 increased to 9380.2 W kg- l |
